Persistence of Adenovirus Nucleic Acids in Nasopharyngeal Secretions

Abstract excerpt

BACKGROUND: Polymerase chain reaction (PCR) assays increase the rate of viral detection in clinical specimens, compared with conventional virologic methods. Studies suggest that PCR may detect virus nucleic acid (NA) that persists in the respiratory tract. METHODS: We analyzed virologic data from children having frequent upper respiratory infections (URI), who were followed up in a longitudinal study....
